Noticed a few seedlings appear to have rust colored leaves.
Above soil 2/8 in nursery bags. repot to 3 Gal and microocto 2/20
LED PPFD 385, 79F, 67% RH
Running Jacks 10-30-20 .5tsp/gal, 3.8ml/gal calmagic, RhizoTonic, GFF, RO water, ph 5.8 drifts up to 6.1,
micro octopot,
3 gal fabric pot Promix bx, perlite 30%
My guess is just a bit of pH drift that caused a touch of lockout during transplant. Top growth looks good. My guess is it’ll hop right out of it. Could be getting hungry as it spreads it’s legs though…if it continues I’d up the food(calmag). Am sure others will throw opinions down too though. Goodluck, my friend 
Thanks for the advice! 
Will do.
